I have a lovebird and a conure, as well as two linnies. Lovebirds are bullies, even to their own species sometimes. My lovebird is female, and they tend to be more aggressive than males. She can be housed next to my other birds, but I only allow her and my conure out together for short, supervised periods of time. Every bird is different though, and you really don't know until you try. But you have to be prepared for separate out of cage time and minimizing jealousy. Usually people will say to assume they won't get along but if they do, then great!
